pptx704 51b5d7b3ba fix: resolve pause/snapshot failures and CoW exhaustion on large VMs ...

Remove hard 10s timeout from Firecracker HTTP client — callers already
pass context.Context with appropriate deadlines, and 20GB+ memfile
writes easily exceed 10s.

Ensure CoW file is at least as large as the origin rootfs. Previously,
WRENN_DEFAULT_ROOTFS_SIZE=30Gi expanded the base image to 30GB but the
default 5GB CoW could not hold all writes, causing dm-snapshot
invalidation and EIO on all guest I/O.

Destroy frozen VMs in resumeOnError instead of leaving zombies that
report "running" but can't execute. Use fresh context for the resume
attempt so a cancelled caller context doesn't falsely trigger destroy.

Increase CP→Agent ResponseHeaderTimeout from 45s to 5min and
PrepareSnapshot timeout from 3s to 30s for large-memory VMs.

After failed pause, ping agent to detect destroyed sandboxes and mark
DB status as "error" instead of reverting to "running".
